A distinguishing characteristic of these sites is how they are moderated:

We designed the Stack Exchange network engine to be mostly self-regulating, in that we amortize the overall moderation cost of the system across thousands of teeny-tiny slices of effort contributed by regular, everyday users.
-- A Theory of Moderation

While there certainly are Moderators here, a significant amount of the moderation is done by ordinary people, using the privileges
they've earned by virtue of their contributions to the site. Each of you contributes a little bit of time and effort, and together you accomplish much.

As we enter a new year, let's pause and reflect, taking a moment to appreciate the work that we do here together.
To that end, here is how the moderation done here on Software Engineering breaks down by activity over the past 12 months:

Footnotes

² The system will suspend users under three circumstances: when a user is recreated after being previously suspended, when a user is recreated after being destroyed for spam or abuse, and when a network-wide suspension is in effect on an account.

³ This counts every review that was submitted (not skipped) - so the 3 suggested edits reviews needed to approve an edit would count as 3, the goal being to indicate the frequency of moderation actions. This also applies to flags, etc.

⁴ Includes close flags (but not close or reopen votes).

⁵ This ignores numerous deletions that happen automatically in response to some other action.

⁶ This includes comments deleted by their own authors (which also account for some number of handled comment flags).
